My wife is also prone to dizziness, but, as grandmag said, Bonnine is fantastic for her, and available on shore at many drug and grocery stores (we get ours at local Jewel). It's a once a day pill, WAY cheaper on shore than on board, and works wonders for her. Another consideration is the location of your cabins. Try and get a cabin mid ship, and some even say a lower deck level. Then,even IF the ship is movong for and aft, the movement will not be so easily felt. Also, just a little aside, they're called SHIPS, not boats. People use boats to drown worms catching fish (sorry, little ship humor there)
